How to scroll down in a listbox?

Question

.NET

The WPF project, in the ViewModel of the list form, binds to the listbox like this:
ItemsSource="{Binding Path=Items, Mode=OneWay}"
When the list list is updated, the contents of the listbox are updated, everything is fine with this.
From what I googled, you can scroll down the listbox like this:

listbox.TopIndex = listbox.Items.Count - 1;
listbox.SelectedIndex = listbox.Items.Count - 1;

I tried to put this code in the SourceUpdated event handler for the listbox - it didn't help.
Maybe you need another event, or another way? How can I auto-scroll listbox?
